The earclip 21 of groove connector 2 is fixed together.Through hole both can be screwed hole or unthreaded hole, as long as can be with screw 41
Coordinate, the earclip 21 of connector 2 is fixedly connected with base 3.By the way of screw 41, cost is low, fastening is firm
Gu it is less prone to loosening.
The through hole being molded on the earclip 21 of slot device connection end is the U-shaped hole of outer openings, is arranged to the U-shaped of outer openings
Hole is advantageous in that, in first can snapping onto U-shaped hole at outer openings of the screw 41 from U-shaped hole in assembling, compared to from upper
Inserted mode under, it is more efficient using this kind of mounting means；In addition, the benefit for being arranged to the U-shaped hole of outer openings also exists
In the mounting hole 111 of screw 41 being arranged into the U-shaped of a side opening so that the installation site of screw 41 can be entered in U-shaped hole
Row lateral adjustments, reduce the precision of through hole.
In embodiments of the present invention, Fig. 5 shows that the structure of the base 3 of the printed circuit-board assembly of the embodiment of the present invention is shown
It is intended to.The thickness range of the base 3 is 1.5-3mm, and the thickness of the base 3 is more than the thickness of the substrate 1.Preferably,
The thickness of the base 3 is 2mm.So set and make it that the bulk strength of printed circuit-board assembly is stronger, in reliability test mistake
It can ensure that printed circuit-board assembly does not rock, and advantageously ensures that the precision of test in journey.The base 3 is towards the substrate
1 plate face is provided with multiple pasting boards 31, and the multiple pasting board 31 is fixedly connected on the base 3 towards the side of substrate 1
In plate face, the fastening structure is fixedly connected on the corresponding pasting board 31.The base 3 is made up of insulating materials, specifically
For epoxy resin.Because the printed circuit-board assembly of the embodiment of the present invention needs to be put into incubator when carrying out reliability test
OK, electric stress and temperature stress are applied.It is that base 3 is being put into the metal of incubator that base 3 is used into effect made of isolation material
Short circuit will not occur with metal bracket when on bracket.
In addition to foregoing description, connector is additionally provided with the printed circuit-board assembly of the embodiment of the present invention, the connector
For with being connected outside incubator, main function to be powered and for current monitoring.
It should be noted that as alternative embodiment, in an embodiment (not shown), the thickness of the substrate 1 is
1mm, the thickness of base 3 is 1.5mm.Another in the embodiment of diagram, the thickness of the substrate 1 is 2mm, the thickness of base 3
Spend for 3mm.
It should be noted that it is golden finger socket that the present invention, which is not limited to connector 2, in other embodiments, insert
Groove connector 2 can also be accessory shoe with electrical contact or test needle type socket.
As alternative embodiment, the substrate is provided with connector mounting groove, is installed in connector mounting groove
There is socket, the socket shares for matching somebody with somebody with the grafting of connector 2, i.e., socket is fixed on into slot first in assembling connects
Connect in device mounting groove, be then arranged on connector 2 on the socket of connector mounting groove by way of grafting.Insert
The back side of seat can protrude slightly above the plane where the back side of substrate 1, so when 20 sockets are arranged on connector mounting groove
Afterwards, the projection formed by socket side by side can be formed at the back side of substrate 1, these projections are by multiple patches on base 3
What the stopper slot 32 that plate 31 is formed coordinated.By setting multiple pasting boards 31 on the base 3 so that multiple pasting boards 31 are spaced shape
Into the stopper slot 32 coordinated with slot, so in assembling, as long as the slot at the back of substrate 1 is snapped onto stopper slot by operator
Contraposition can be achieved in 32, improve installation effectiveness.
In addition, the present invention also provides a kind of reliability test system with above-mentioned printed circuit-board assembly, the system is also
Including multiple circuit-under-test plates 5, in reliability test, circuit-under-test plate 5 is plugged on printed circuit-board assembly be powered into
Row detection.Circuit-under-test plate 5 includes but is not limited to Medical Devices circuit-under-test version.
Although being described in conjunction with the accompanying embodiments of the present invention, those skilled in the art can not depart from this hair
